He coordinates of the vertices of △jkl are j(3, 0) , k(1, −2) , and l(6, −2) . the coordinates of the vertices of △j′k′l′ are j′(−3, 1) , k′(−1, 3) , and l′(−6, 3) . which statement correctly describes the relationship between △jkl and △j′k′l′ ? △jkl is congruent to △j′k′l′ because you can map △jkl to △j′k′l′ using a translation 1 unit up followed by a reflection across the y-axis, which is a sequence of rigid motions. △jkl is congruent to △j′k′l′ because you can map △jkl to △j′k′l′ using a reflection across the x-axis followed by a reflection across the y-axis, which is a sequence of rigid motions. △jkl is congruent to △j′k′l′ because you can map △jkl to △j′k′l′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions. △jkl is not congruent to △j′k′l′ because there is no sequence of rigid motions that maps △jkl to △j′k′l′.

As Given :The coordinates of the vertices of △JKL are J(3, 0) , K(1, −2) , and L(6, −2) . The coordinates of the vertices of △J′K′L′ are J′(−3, 1) , K′(−1, 3) , and L′(−6, 3) .

⇒As we can see the two triangles are congruent because length of sides are equal.i.e By SSS  ΔJKL and ΔJ'K'L' are congruent.

⇒ As you can see from the figure depicted below the triangle JKL is rotated by an angle of 180° then translation of y coordinate by 1 unit up has taken place.

So , Option (3) is correct which is :△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
